Health Minister Anbumani Ramadoss said: "The situation is not that of an epidemic and we expect that the number of dengue cases will see a decreasing trend in the next two-three days.
"So far we have recorded 2,900 cases of dengue from across the country. I would like to say that in spite of the above numbers, the situation is under control. We are not complacent and the situation is a matter of concern to the government."
He also briefed the cabinet meeting chaired by Prime Minister Manmohan Singh, three of whose family members are feared to have been affected by dengue, on the steps taken to contain the disease.
"There is absolutely no need for panic," Information and Broadcasting Minister P.R. Dasmunsi said after the cabinet meeting here.
Dengue is caused by the bite of Aedes Aegypti, a type of mosquito, that breeds in stagnant water.
The dengue outbreak usually erupts as the annual monsoon tapers off across the country, leaving behind countless small pools and puddles of stagnant water.
The worst affected by the dengue virus is the capital where one more patient died, taking the death toll to 17 even as over 50 fresh cases were reported Thursday.
Laxmi Narayan, 55, a resident of Bulandshahar in Uttar Pradesh, was the latest victim of dengue at the All India Institute of Medical Sciences (AIIMS), the country's top public hospital.
"Narayan was admitted to the hospital this morning in a serious condition but he succumbed to the ailment at around 2 p.m.," said AIIMS medical superintendent D.K. Sharma.
"Till forenoon (Thursday) we have recorded 16 deaths and one more person has died at AIIMS this afternoon," said N.K. Yadav, chief municipal officer of Delhi.
According to health officials, the number of dengue patients could go up further as the data compilation of all hospitals in the city had yet to be completed.
Two grandsons of Prime Minister Manmohan Singh - Rohan (11) and Madhav (17) - were being treated at AIIMS for "suspected" dengue symptoms. Manmohan Singh's eldest son-in-law Vijay Tankha, a professor at St. Stephens College here, has also been admitted to the hospital for similar symptoms.
AIIMS doctors said the prime minister's family members were recovering well.
"We are conducting blood tests every six hours. We suspect dengue. But the final results will be known only Friday evening," said a doctor.
Acting on a petition, Delhi High Court Thursday sought explanations from the central and Delhi governments as well as the Municipal Corporation of Delhi (MCD) on their failure to deal with the outbreak of dengue in the capital.

She said that it was not confirmed if a death in Faridabad was due to dengue.
The government Thursday set up a testing laboratory in Panchkula town adjoining state capital Chandigarh as six to seven suspected dengue cases were reported from Panchkula district during last two days.
In Punjab, the number of suspected dengue cases in various places was well over 150, with nearly 90 of them in industrial hub Ludhiana itself.

In Karnataka, the Health and Family Welfare Department intensified surveillance in capital Bangalore and select districts to prevent the outbreak of dengue fever and chikungunya.
"The situation in Karnataka is under control. We have stepped up anti-mosquito and anti-larva measures in susceptible areas to prevent dengue. Extensive fumigation and spraying of chemicals have contained the spread of chikungunya," H.C. Ramesh, joint director for malaria and falaria, told IANS.
Though the health and civic authorities have managed to bring chikungunya under control, with less than 1,000 cases being reported a week across the state, dengue has claimed four lives out of 59 cases reported this year.
The neighbouring Andhra Pradesh has recorded no dengue cases this season, but authorities were on alert to prevent any outbreak.
"The state government is totally equipped to tackle dengue," said Venkateswara Rao, director of health services.
